SOlL-PULVERIZER.-

SPECIFICATIOliTforming part of Letters Patent No. 278,803, dated June 5, 1883.

Application filed February 52 6, 1883 (No model.)

ToaZZ whom, it may concern:

Be it known that I, ROBERT BURNs LILLIE, of Hanover, in the county of Grafton, of the State of New Hampshire, have invented a new and useful Improvement in Soil-Pulverizers and I do hereby declare the same to be described in the followingspecification and represented in the accompanying drawings, of which Figure 1 is a top view, Fig. 2 a side elevation, Fig. 3 a longitudinal section, and Fig. 4 a transverse section, ofa soil-pulverizer embodying my invention, the nature of which is defined in the claims hereinafter presented. Figs. 5, 6, 7, and 8 are hereinafter explained.

In the said drawings, A denotes a frame provided wit-h a tongue, B, to which a rocl erlever, C, is pivoted at its middle, such lever being furnished with two whiffletrees, D D, arranged as shown. This tongue and these whiffietrees are for applying horses or draftanimals to the machine. WVhen oxen are used the rocker-lever and whiffletrees may be dispensed with.

Extending transversely under the frame A, and firmly secured to it, is an axle, E, upon whose journals c a two wheels, F F, are placed, they revolving freely on the said journals.

XVithin the hub of each wheel is an internalratchet, b, ,which is particularly shown in Fig. 5, such being an inner side view of the hub of the wheel. Against each hub, and to revolve freely on the axle, is a gear, G, a side view of the hub of which without its two pawls p 1) being given in Fig. 6. A. top view of one of such pawls is shown in Fig. 7, while Fig. 8 shows a view of the hub with its pawls. The hub has two cylindrical holes, 0 0, each being to receive a pivot of one of the pawls. Besides these holes there are two curved slots, 6 e, in the hub, each of which is to receive a tooth,

f, projecting from one of the pawls. These pawl-teeth go through the slots in the hub of the wheel and extend into a cylinder, 9, which is; grooved peripherally, and is concave on its outer side, and, besides, is adapted to slide on the axle lengthwise thereof.

two arms of a hand-lever, 7c, fulcrumed t0 the axle; This lever works against the face of a stationary sector or standard, I, in which are or may be two holes to receive a stud projecting from the lever, such holes and stud serving to determine the extreme positions of the levler. On the lever being moved one waythe two concave cylinders 9 will be forced toward the two gears, and, acting against the teeth f of the two pawls p p, will move and hold the pawls in, so as to keep each in engagement with its ratchet b. On the lever being moved the opposite way the pawls will be set free to engage with the ratchets b of the two wheels F F, and as a consequence the gears G will be revolved by the said wheels. When the pawls Z it series of pulverizers or stars, H, each of which consists of a hub, r, and a set of long teeth, .9, radiating from it, the hub being arranged on the shaft q concentrically and fixed to it by aset-screw, 15. Such mode of applying and fastening each star to its shaft enables a person to vary the positions of the teeth of one star relatively to those of the stars next to it as occasion may require, and, besides, it enables more or less of the stars to be removed from their shaft and the remainder arranged apart from each other and with reference to the fellow set of stars as convenience or necessity may dictate.

A tubular shaft, I, supported by and so as to be capable of revolving in two arms, K K, extending down from the axle, has within it concentrically a solid shaft, L. The two gears n n revolve freely on the latter shaft. Furthermore, one of the star-shafts q is j ournaled, near one end of it, in an arm, a, projecting from the tubular shaft 1, the other star-shaft being journaled in another arm, 1), projecting from solid shaft L. q q, near their opposite ends, are journaled in the lower arms of two knee-levers, M and N, one of which, at its middle, is fixed to the tubular shaft I, and the other at its middle to The said two star-shafts IOO the solid shaft L. The upper arms of the two knee-levers are, by links 0 0, connected with the two arms of a hand-lever, P, fulcrumed on the axle, such hand-lever having to its longer" arm a lever-pawl, R, to engage with the teeth of a stationary arched rack, S, fixed to the frame A and arranged as represented.

By moving the hand-lever the shafts q (1 may be caused to simultaneously approach or recede from each other, in order to bring the pulverizingstars of one shaftnearer to or farther from those of the other, as may be desirable, or to cause the stars of one set to enter and play between those of the other, in which latter case they would act like shears to cut or shear as well as to pulw'erize the soil. As the two constellations or sets of stars are moved apart from each other they also rise upward, a contrary effect resulting as they approach each other, from which it will be seen that they may be raised entirely oft the ground or (lepressed so as to enter it to any desirable depth within the length of one of their teeth.

The seat for the driver of the machine is shown at U, it being arranged so that he can readily reach and manipulate each of the two hand-levers.

hen the machine is being drawn torward and the pawls are in action on the ratchets b the two sets of pulverizing-stars will be put in revolution, and if in contact with the ground will reduce or break it up or pulverize it. By throwing the pawls out of action on the ratchets and raising the stars off the ground no revolution of such stars will take place, and the wheels can revolve either way without produc ing any such movements of the stars.

In practice the machine will operate with great ease and to excellent advantage in breaking up and pulverizing soil for agricultural purposes.

I claim l. The combination, substantially as described, for supporting and elevating and (1epressing the shafts, of the two sets of pulver izing-stars, such combination consisting of the tubular shaft 1, solid shaft L, arms u and 2:, knee-levers M and N, links 0 O, and handlever P, all being arranged and adapted to op erate essentially as set forth.

2. The combination of the i'nechanism for supporting and elevating .or depressing the shafts of the two sets of pulverizing-stars (such consisting of the shafts I and L, arms u and r, knee-leversJlI and N, links 0 O, and handlever I?) with the mechanism for revolving the shafts of the two sets of stars by means of the wheels F F,-sueh mechanism consisting of the ratchets'b, the two geantrains G m n o 0, and the pawls of the gears G, such pawls being provided with mechanism for operating them or forcing and holding them out of engagement with the ratchets, as set forth.
